Barometer/altimeter part 1:
meter with many facilities
It is just about ten years ago that this magazine published the design of a barometer/altimeter. In these ten years electronics technology has progressed to developments that were unimaginable then. The present barometer/ altimeter is based on a precision airpressure sensor with integral signal processor from Motorola. Evaluation, storing, display and interchange of data are effected by a microcontroller system.
